Rapid Quality Index (R-MaQI), based mainly on macrophyte associations, to assess the ecological status of Mediterranean transitional environments

Abstract

A rapid index for the quality status assessment of Mediterranean transitional environments is proposed. It is based on the study of macrophyte associations (macroalgae and seagrasses) and the gross determination of some environmental parameters. The index was set up in 19 sampling sites of the Venice lagoon monitored during one year on a monthly basis taking into account the flora, the main contaminants and some other variables indicating the presence of gradients of stress conditions. Results were compared and intercalibrated with measurements carried out in Sacca di Goro, placed in Po delta, and in Lesina and Orbetello lagoons.
